[GokuUltraInstinct]

Im try both dev versions from downloading page and have the same problem - after first run (i only changed JIT to IR-Interpreter in dev option) all working good with 55-60 fps on iPhone 5s but on second run emulator stuck and after 1-2 minutes whole phone stuck rebooting and reinstalling through Cydia Impactor not fix this. If someone know what settings or version i need to use please write this here. Sorry for my poor english.
